The LT
®
1101 establishes the following milestones:
(1) It is the first micropower instrumentation amplifier,
(2) It is the first single supply instrumentation amplifier,
(3) It is the first instrumentation amplifier to feature fixed
gains of 10 and/or 100 in low cost, space-saving 8-lead
packages.
The LT1101 is completely self-contained: no external gain
setting resistor is required. The LT1101 combines its
micropower operation (75µA supply current) with a
gain error of 0.008%, gain linearity of 3ppm, gain drift of
1ppm/°C. The output is guaranteed to drive a 2k load to
±10V with excellent gain accuracy.
Other precision specifications are also outstanding:
50µV input offset voltage, 130pA input offset current, and
low drift (0.4µV/°C and 0.7pA/°C).
In addition, unlike other
instrumentation amplifiers, there is no output offset
voltage contribution to total error.
A full set of specifications are provided with ±15V dual
supplies and for single 5V supply operation. The LT1101
can be operated from a single lithium cell or two Ni-Cad
batteries. Battery voltage can drop as low as 1.8V, yet the
LT1101 still maintains its gain accuracy. In single supply
applications, both input and output voltages swing
to within a few millivolts of ground. The output sinks
current while swinging to ground—no external, power
consuming pull down resistors are needed.
